How exactly does the choice of delimiter affect whether or not a regex will work (in the way intended)?
I decided to use ActivePerl to do edit a bunch of SQL saved in a text file:
perl -p -e "s/(.*?)\.(\w\w\w),/iif([month]>,$1.$2,0) as $2/" temp.txt
did not match

perl -p -e "s|(.*?)\.(\w\w\w),|iif([month]>,$1.$2,0) as $2|" temp.txt
did match.
???
